R.I. sports betting numbers improved in March, but remained below expectations Patrick Anderson, Providence Journal · April 23, 2019 at 12:05 am March was the best month ever for Rhode Island’s nascent sports betting operation, but still fell far short of the revenue the state anticipated when it legalized athletic wagering last year. Sports Book Rhode Island made $1,548,230 in March, a high-volume month that includes the NCAA basketball tournament. It was a significant improvement from February, when the house lost nearly $900,000 to gamblers. The state receives a little more than half of all sports betting revenue, which would put its March take at around $775,000. Although that’s a step in the right direction, the budget lawmakers passed last summer assumed $23.5 million in sports betting revenue, or nearly $2 million per month.
